Abstract (en)
The present disclosure relates to methods of producing a packaging container (1) for bulk solids. The packaging container (1) comprising an inner compartment (2) and a transport closure (13) closing the inner compartment (2), the transport closure (13) being provided, on a first side (13a) of the transport closure (13), with a one-way pressure relief valve (15) for allowing gas in the inner compartment (2) of the packaging container (1) to exit therefrom, the transport closure (13) being provided with at least one through perforation (16) covered by the valve (15) on a first side (13a) of the transport closure (13), the method comprises the steps of:a) forming a tubular container body (3), the container body having an upper end (4) with an upper body opening (5) and a bottom end (6) with a bottom body opening (7);b) presenting the container body (3) to an upper body opening sealing station (28) comprising a plunger piston (29) comprising a bottom plate (30), the bottom plate (30a) having a through hole (31) extending from a first side (30a) of the bottom plate (30) to a second side (30b) of the bottom plate (30a);c) closing the upper body opening (5) by pressing the transport closure (13) with the plunger piston (29) into the upper body opening (5) such that a pressure above an ambient pressure is produced within the tubular container body (3) on a second side (13b) of the transport closure (13), allowing gas to exit the valve (15) and the valve (15) to be pre-conditioned; andd) attaching the transport closure (13) to the inner surface (9) of the container body wall (8).
